The first semifinal at the Miami Open is set and it features US Open runner-ups Caroline Wozniacki against Karolina Pliskova, after both scored comprehensive straight set wins on Tuesday.

Pliskova reached her first Miami semifinal beating Mirjana Lucic-Baroni 6-3, 6-4 and avenging her loss to the Croat at the Australian Open.

“I think I played much better here than I was playing [in Melbourne],” Pliskova said. “Also, the conditions here are different, and she was playing better tennis there because it was faster. It suited her better in Australia.

“So definitely I was feeling more confident with this match. I had a different game plan today.”

The Czech was aided by 10 double faults from Lucic-Baroni, nine in the first set!

Wozniacki took the court in the evening against a red-hot Lucia Safarova. But the Dane cooled her down taking the match 6-4, 6-3.

Wozniacki has won three of four against Pliskova but Karolina won their most recent meeting in the Doha final last month. Wozniacki took their only Miami meeting in three sets in 2013.

“Obviously against Caroline, we played in Doha also, so a little bit different conditions than here,” Pliskova said. “I would expect tough one because I know she has been playing quite good here in last few years.”
